Abstract
An electronic circuit with a trimming capacitor with a first electrode in the form of a flexible sheet metal lug which is arranged in confronting relationship with a rigid counter electrode in the form of a plate capacitor. The flexible sheet metal lug and the plate capacitor are rigidly connected to an insulating support, for example a circuit board, and the capacitance of the trimming capacitor can be adjusted by bending the sheet metal lug.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. An electronic circuit with a trimming capacitor consisting of a flexible metal lug as a first electrode and a rigid counter electrode, said metal lug being arranged in confronting relationship with said counter electrode, characterized in that: said counter electrode is formed by a plate capacitor rigidly connected to an insulating support; said metal lug being bendable for varying the capacitance of the trimming capacitor; said metal lug being soldered to said insulating support; and said metal lug being a strip of a band of tin.Join the waitlist — get patent alerts
